Ok, the bible tells us that Noah was tasked with preserving 2 of every kind of animal that was considered “unclean” and 7 for every type of “clean” animal. Given all the species of animals that’s quite a big number of animals living in that Ark. What do you think Noah and his family did with all that excrement? I don’t think they burned it since the Ark itself was made of wood and that could have set the whole ship ablaze.

Animal diapers perhaps?

I've been presented this question by several evolutionists and have never been able to provide a plausible solution to this problem
